1970 Duster AlterKtion, 4 Link, LS/T56/Turbo and Minitub
Dropped the block off at the machine shop today. After Jerry (guy who runs the shop) looked at the pistons and bearings he said it was definitely detonation that killed it from too much timing. Just very odd it was only 1 bank. Hes never seen that before. I'm going to check my flex joint because I've been reading some nightmares about those collapsing. He said the block really should be bored over at this point but then we'll have to pull the cam bearings and basically start over so I'll have a $1500 bill again. Not worth it for a 5.3 when I have a 6.0 up in Vermont I'm going to build this winter. So I ordered some stock 4.8 gen 4 flat top pistons, gave him my gen 4 rods I had ordered and we're just going to slap this block back together sloppy style with some honing and send it until I build the 6.0. He said this will work fine but it may need rings again by 50 or 60k miles because of how much we'll have honed the cylinders. But I'll never put that many miles on this motor since it's going to go into my CJ when the 6.0 goes in this.
Once its back together I'll be back to the dyno, possibly a different dyno.
